This study is the first known to use network meta-analysis to simultaneously evaluate the effectiveness of interventions to increase the prevalence of functioning smoke alarms in households with children. The authors identified 24 primary studies from a systematic review of reviews and of more recently published primary studies, of which 23 (17 randomized controlled trials and 6 nonrandomized comparative studies) were included in 1 of the following 2 network meta-analyses: 1) possession of a functioning alarm: interventions that were more "intensive" (i.e., included components providing equipment (with or without fitting), home inspection, or both, in addition to education) generally were more effective. The intervention containing all of the aforementioned components was identified as being the most likely to be the most effective (probability (best) = 0.66), with an odds ratio versus usual care of 7.15 (95% credible interval: 2.40, 22.73); 2) type of battery-powered alarms: ionization alarms with lithium batteries were most likely to be the best type for increasing functioning possession (probability (best) = 0.69). Smoke alarm promotion programs should ensure they provide the combination of interventions most likely to be effective.

网络荟萃分析评估干预措施的有效性，以增加烟雾警报器的使用。

这项研究是已知的第一个使用网络荟萃分析同时评估干预措施的有效性，以增加有孩子的家庭中功能性烟雾警报器的普及率。作者从系统评价和最近发表的主要研究中确定了 24 项主要研究，其中 23 项（17 项随机对照试验和 6 项非随机比较研究）被纳入以下 2 项网络荟萃分析中的一项：1）拥有功能警报：更“密集”的干预措施（即，除了教育之外，还包括提供设备（带或不带配件）、家庭检查或两者兼有的组件）通常更有效。包含所有上述成分的干预被确定为最有可能是最有效的（概率（最佳）= 0.66），与常规护理的优势比为 7.15（95% 可信区间：2.40、22.73）；2）电池供电的报警器类型：锂电池电离报警器最有可能是增加功能拥有的最佳类型（概率（最佳）= 0.69）。烟雾警报推广计划应确保提供最有可能有效的干预措施组合。
